--- Comment #3 from Luboš Luňák <l.lunak at collabora.com> ---
This has nothing to do with Skia, in fact AFAICT Skia still performs the best
here.

It's either a problem of Writer redrawing too much, or
VclProcessor2D::RenderMaskPrimitive2DPixel() thinking that implementing
clipping using transparency is a good idea.
